A novel non

We report transport and thermodynamic properties of stoichiometric single crystals of the hexagonal iron-pnictide FeCrAs. The in-plane resistivity shows an unusual “non-metallic" dependence on temperature T, rising continuously with decreasing T from ~ 800 K to below 100 mK. The c-axis resistivity is similar, except for a sharp drop upon entry into an antiferromagnetic state at TN ~ 125 K. Below 10 K the resistivity follows a non$\hbox{--} $Fermi-liquid power law, $\rho (T)=\rho _{0}-AT^{x}$ with x < 1, while the specific heat shows Fermi-liquid behaviour with a large Sommerfeld coefficient, γ ~ 30 mJ/mol K2. The high-temperature properties are reminiscent of those of the parent compounds of the new layered iron-pnictide superconductors, however the T $\rightarrow$ 0 K properties suggest a new class of non-Fermi liquid
